hello:

    In rare cases, iMX.RT1050 board dcdc can't work with the voltage is 0v. But under normal condition,the output is 1.25v with 528Mhz. Power up again the failure  is removed.It is a new developed board, I think the overcurrent is more possible . the datasheet metion that  dcdc has Over current protection,Over voltage protection and Low voltage detection。

1)Whether some register can record  the wrong time?

2)  DCDC Register 0  is  the settings as follows with reset。whether the 8/11/17 is open or closed?

3)whether it can close the the  overcurrent/ low voltage /high voltage or not ?  the setting is"1" is right?
